More Information RedVox Infrasound Recorder is an Android app (no longer available for iOS) that allows you to record low-frequency sounds generated by volcanic eruptions, sonic booms, meteors, earthquakes, and other significant audial events. Infrasound Recorder records this audio using your smartphone's microphone and, if available, barometer. The app saves recorded audio as RDVXZ files. On Android devices, Infrasound Recorder stores RDVXZ files in a folder named RDVXZ . If users want to analyze the audio their RDVXZ files contain on their PC, they can do so by copying the files to their computer.
